SARASOTA, Fla. – Ubaldo Jimenez is here in Orioles camp again today. His four-year deal is not official yet -- he still must finalize his physical -- but an announcement from the team could come at some point today. Regardless, the Orioles wouldn't hold a news conference to introduce him until Thursday.

Jimenez has a locker in the Orioles clubhouse here in Sarasota. According to the name plate, he will wear No. 31.

Jimenez will take the No. 31 jersey from right-hander Kevin Gausman – who is switching his uniform number for the second time this offseason. He switched to two weeks ago to give his old No. 37 to new pitching coach Dave Wallace. Now he'll wear No. 39.

Gausman said that some fans were upset with him on Twitter following his last number change because they had gone out to purchase Gausman's No. 37 jersey, which he has worn since he was called up to the majors last season. He said he signed a number of No. 37 jerseys at FanFest earlier this month.

Orioles right-hander Miguel Gonzalez said this morning that he plans to throw a bullpen session today to test his back.

Gonzalez, who hasn’t been on the mound since leaving Saturday’s workout with back spasms, said he will throw 20 pitches.

“Nice and easy,” Gonzalez said. “I feel good. We’re going to see how it goes. The trainers told me to stop if I feel anything.”

Gonzalez has said he’s not worried about the setback since he’s been working out in Sarasota for three weeks and has already thrown a handful of bullpens.

South Korean right-hander Suk-min Yoon will throw his first bullpen session as an Oriole today.

Pitchers fielding practice drills will include working on fielding bunts down the third-base line, wild pitch coverage, squeeze plays and comebacker plays.

This will be the first official full-squad workout of spring training, even though most position players have already reported and began working out on their own. Everyone has reported, including the final two players to arrive – Francisco Peguero and Michael Almanzar.
